[Leica] comparison of 4 noise reduction programs

[Don Dory]

Greetings to all.  The attached files are the same image processed in 4
noise reduction programs.  The base image was shot at 25600 ISO and cropped
to less than 50% of the image.  The camera was a Sony A1 and the lens was a
Sigma 105 F1.4 at 1.4.  Take a look and decide, the only processing was the
noise reduction, cropping, and lightening the overall image.

First is LR enhance:
